Re: CRAWL SPACE VENTS
Here is North Carolina we have 90% humidity with 90 degree heat in the summer. The crawl space area is cool. Guess what happens. The humid air goes into the cool crawl space and condenses. The air circulation attempts to dry the space out but the air is so humid, it is difficult for it to absorb more.
The best idea is to close the crawlspace, insulate the walls, vapor barrier on floor and walls, and condition the space.
Most of the homes around here have 75%-95% of the crawl space floor covered with vapor barrier. New construction is approaching 100% coverage.
If the client is not going to close and condition the space, then ventilate. At least some of the moisture will evaporate.
